PAPER-SLITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 672,899, dated April30, 1901. Application filed January 10, 1901. Serial No. 42,729. (Nomodel.)

To all whom it may concern:

Be it known that I, JULIUS F. HAASCH, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, haveinvented certain new and useful Improvements inPaper-slitting Machines; and I do hereby declare that the following is afull, clear, and exact description thereof.

Heretofore, so far as 1am aware, newspaper and periodical mailing-lists,printed several columns to the sheet, have been laborie ously, slowly,and oftentimes unsatisfactorily cut by hand with scissor-type shears,the la- :5 bor being at all times trying and frequently painful to thoseemployed at such work.

To provide a simple economical machine by which to easily, rapidly, andsatisfactorily cut lists of the kind aforesaid is the especial 2o objectof my invention, said invention consisting in certain peculiarities ofconstruction and combination of parts hereinafter particularly setforth, with reference to the accompanying drawings,and subsequentlyclaimed.

Figure 1 of thedrawings represents a sectional view of a paper-slittingmachine in accordance with my invention, this view being indicated bylines 1 1 in the second figure,

and Fig. 2, a partly-sectional end elevation of 0 said machine.

Referring by letter to the drawings, A indicates each of a pair ofstandards braced -apart by suitably-arranged bars B, one of which isshown in Fig. 1. A headpiece C is 5 bolted at its ends to the upperextremities of the standards, and longitudinal slots are provided insaid standards.

The assemblage of parts above specified constitute a frame that may bemade for attachment to any convenient support or of itself constitute asupport for one end of a table D, as herein shown.

Fitting the slots in standards A are boxes E F for journals of parallelshafts G H, the lower one of which is provided with a crank or othermeans for the application of power. Engaged by the counter-shaft are thehubs of a series of rollers K, in the form of cylindrical shells, andthese rollers are held in ad- 5o justed position on said shaft by meansof setscrews J, that turn in said hubs, these screws being in registerwith tool-apertures in the roller-rims. Similar rollers I, of preferablygreater diameter than those aforesaid, are likewise held in adjustableposition on the power-shaft, and, as herein shown, the rollers K arepreferably covered with bands L, of rubber or other suitable flexiblematerial. Screws M, run through set-nuts N, and headpiece 0 of themachine-frame impinge the.

journal-boxes E, and thus an adjustable tension of the band-coveredrollers K is had upon material passed between them and the'ones, I, onthe power-shaft.

Bolted to heads of rollers K are cutter-disks P, that lap the rim edgesof the rollers I, these disks being kept sung in working position by theexpansive force of a spiral spring Q, arranged on shaft G undercompression between one of said disks and a washer adjacent to ajournal-box for said shaft.

A sheet of paper on which mailing-lists are printed in columns is fedfrom table D or other support between the opposing rollers I K, sothatthe disks P will slit the paper between said columns, rotary motionbeing imparted to one set of rollers by turning the shaft to which theyare connected and communicated by friction to the other set of rollers,whereby said paper is drawn forward in time with the slitting operation,the covering L on rollers K serving to cushion the aforesaid paper andto prevent tearing of same.

The operator starts the sheetof paper and guides the same, so as toinsure against cutting into the columns of printing thereon, and thework is rapidly performed with but little effort on the part of saidoperator, all the columns on said sheet being cut out at the same time,the number of rollers in each series and that of the cutting-disks beingproportionate to the number of said columns and provision had by properspacing of said rollers to leave sufficient margin on each side of eachcolumn of printed matter on each strip as it comes from the machine.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A paper-slitting machine comprising a frame, power and counter shaftsjournaledin boxes'engaging slots in frame-standards, a series ofopposing feed-rollers on the shafts each roller consisting of acylindrical shell having a tool-aperture in its rim and a shaftfittinghub provided with a set-screw in register with said aperture;cutting-disks bolted to heads of one set of rollers to lap rim edges ofthe other set, a spiral spring under compression between a cutting-diskand journalits rim and a shaft-fitting hub provided with a set-screw inregister with said aperture; cutting-disks bolted to heads of one set ofrollers to lap rim edges of the other set, a spiral spring undercompression between a cutting-disk and journal-box of the shaft carryingthe roller to which said disk is secured, and means for regulatingfriction between opposing rollers.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
